SUPPORT FOR SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 409,638, dated August20, 1889.

Application filed May 24, 1889- Serial No. 311,959. (No model.)

To all whom it may concern.-

Be it known that I, BENJAMIN N. GooDALE, of Saco, county of York, Stateof Maine, have invented an Improvement in Supports forSpinning-Spindles, of which the following description, in connectionwith the accompanying drawings,is a specificatiomlike letters 011 thedrawings representing like parts.

IIeretofore great effort has been made and many inventions have beenpatented having for their aim the production of improved bearings forspindles, whereby the same could be run at high speed and carry anunbalanced load.

In my experiments to produce a bolsterbearing which would permit thespindle to have sufficient looseness to run with anunbalanced load athigh speed I have devised a bolster bearing the interior of which isfaceted, thus forming plain surfaces, againstwhich the spindle bearswhen being rotated,

and in practice the diameter of the spindle where it enters the facetedbearing is enough smaller than the diameter of the opening in thebolster-bearing that the spindle bears against two, at least,of thefacets of thebearings, leaving a space between for oil.

My invention consists, essentially, in the combinationnvith averticalspindle and step, of a faceted bolster-bearing, substantially as will bedescribed.

' Figure 1, in partial elevation and section, represents a spindle andbolster-bearin g therefor embodying my invention. Fig. 2 is a sectionbelow the dotted line 00, Fig. 1; and Fig. 3 is a similar section of amodified form of my invention.

The supporting-case Alias its shank A extended through the rail A andbelow the rail the shank has applied to it a nut A", of usualconstruction. The supporting-case has at its lower end a step a, shapedto sustain the weight of the spindle B and to let the foot of thespindle move laterallythereon, as required, as the spindle seeks to findthe center of rotation of the load, and at its upper end the said casehas a bolster or lateral bearing (1, the interior of which is faceted orprovided with a series of faces, as best shown in Figs.

its rotation.

111 Fig. 2 the bolster-bearin g has three facets with spaces between foroil, While in Fig. 3 the bolster has four facets; but in action,when thespindle rotates, the latter is drawn to and rotates in contact with buttwo of the facets or faces.

I do not desire to limit my invention to the exact number of facets solong as there are two or more.

I am not aware, prior to my invention, that the bolster-bearing for aspinning-spindle has ever had a faceted inner surface.

I have shown my improved bolster-bearing as employed with a sleeve-whirlspindle, with which class of spindle it possesses peculiar advantages;but I do not desire to limit my invention in bolster-bearings to itsemployment only with a sleeve-whirl spindle, as the said bolster-bearingmay be advantageously used with other usual forms of spinning-spindles.

In my invention, as herein illustrated, the looseness for the spindle isprovided by making it of somewhat less diametenas stated, than the innerdiameter of the bolster-bearmg.

In Figs. 2 and 3, wherein the spindle is represented in section, it willbe seen that the spindle does not actually contact with thebolster-bearing, but as soon as the band is applied to the spindle itwill be immediately aligned, so as to cause the spindle to touch two ofthe facets, the two facet-s so touched depending upon the direction inwhich the band-pull is exerted.

I claim- The combination, with a spindle and step, of a facetedbolsterbearing, substantially as described.

In testimony whereof-I have signed my name to this specification in thepresence of two subscribing witnesses.

BENJ. N. GOODALE.
